The changes, which will take place on August 16, will mean Mr Spreadbury will be able to invest in non-sterling corporate bonds.
At present the fund’s investment objective is to achieve its income from a portfolio primarily invested in sterling-denominated fixed interest securities but this will be changed to include other bonds hedged back to sterling.
The group said the move would not increase the fund’s currency risk though as non-sterling exposure would be hedged.
“As well as providing the fund manager with the opportunity to invest in a more diverse range of securities, allowing exposure to non-sterling denominated investments will also be beneficial to the fund as it will provide additional liquidity and maintain the fund’s potential to deliver consistent performance over the long term,” the company said.
The fund will remain in the IMA Sterling Corporate Bond sector.
It has delivered a second quartile return of 48.3 per cent in five years to May 24 compared with the benchmark sector’s 40.4 per cent average return, according to FE Analytics.
